The team will be expected to design, analyze, and wind-tunnel test a model that develops the understanding of the benefits of using the Coanda effect to minimize the negative impact of compressor hub cavity recirculation into the main gas path of a turbofan high pressure compressor. The team will need access to software to create 3D models and to execute computational fluid dynamics (CFD) and finite element (FEA) analyses. A preliminary statement of work includes:
1) Perform aerodynamic and mechanical analyses of an airfoil cascade at predicted rig test condition without hub injection. Includes method of assembly and installation into Educational Wind Tunnel
2) Design a pressurized secondary flow system that can introduce the stator hub flow during testing of the model in the Educational Wind Tunnel
3) Update the aerodynamic model to include stator hub injection representative of current and Coanda-influenced configurations
a. This model may need to be simplified as a simple source term at the hub as opposed to modeling the geometry depending on CAD/CFD proficiency
4) Manufacture or procure all test hardware including instrumentation to measure cascade exit conditions and quantify the benefit of the Coanda-directed design
a. Many of the parts may be 3D printed, including the airfoil
5) Analyze the data, make comparisons to analytical predictions, and generate a final report that describes the program, the benefits of the Coanda-directed design, and any recommendations based on lessons learned during the project
